This paper presents a motion control algorithm for a multiple mobile autonomous agents using the concept of a rigid and persistent formation with a Leader-Follower structure. Initially, a triangular formation was started for three agents and subsequently Henneberg Sequence [4] is applied to extend for multi-agent system. A decentralized control for each agent considering the shortest path between its initial & final position during the motion of formation is developed using SQP-a nonlinear optimization technique.
